My new P-3 Pro battery won't upgrade, (I still get the red "battery requires new upgrade"). Did a search and I have followed all the videos on this forum. The SD card with the latest bin file IS in the bird: Firm 1.3.20 - App 2.0.2 .Original battery is A-Okay. Have tried updating the battery with the RC both on and off. Nada. Can I fly with that new battery? I'm thinking no. - Wazzzup ???!!!
